❖ This is a sound postcard and a pair of used admission tickets sold at Portopia '81 (Kobe Port Island Exposition), held in 1981 to commemorate the opening of the artificial island Port Island. The postcard is a record. ❖ The postcard itself is clean, so I think it can be played, but I can't confirm it because I don't have a player. However, the outer cover case has stains and folds due to aging. Please refrain from purchasing if you are concerned about this. The tickets are used, so they have creases. ❖ It has been in my house for a long time, but it came out during a decluttering session. I remember getting it at Hoshidensha, an electronics store in Sannomiya, Kobe, at the time. I thought it was a rare and valuable item, so I decided to put it up for sale. ❖ I would be grateful if you would add it to your collection.
